EOI’s electrolytic ozone technology generates ozone directly in-water from-water; an anode and cathode are placed in contact with opposite sides of a proton exchange membrane (PEM), power is supplied to the cell and water flowing over the surface of the anode breaks down into hydrogen atoms and oxygen atoms that assemble to form O3 (ozone)

Corona discharge ozone technology generates ozone through the use of a corona discharge tube, using oxygen from the surrounding air; high off-gas levels, system complexity, space requirements, and ambient humidity make this technology unsuitable for compact applications, such as point-of-use water disinfection and surface sanitization

Ultraviolet (UV) light ozone generators generate ozone at lower concentrations and are less efficient in fast-moving stream or on-demand application
